LONDON, May 15 (Reuters) - Operator Royal Dutch Shell lifted the force majeure in place on exports of major Nigerian grade Bonny Light, as tight global oil supply encourages sellers of Nigerian crude to offer many varieties at all-time high prices.

NIGERIA

* Feeding the Bonny Light terminal, the Nembe Creek Trunk Line has been struck by three outages this year, worrying traders, although loading delays have only been around five days.

* Around 20 Nigerian cargoes still remain from the June programme, while Nigeria’s new programmes are due next week.

* Demand is seen to be strong in Western markets given relatively high European gasoline cracks and the transition to a more expensive gasoline blend for the U.S. summer driving season.

* U.S.-based Marathon Petroleum is set to take a VLCC of a West African grade to the U.S. Gulf coast, loading in June, its third such shipment in three months.

* The IEA cited economic deceleration in Nigeria, along with Brazil and China, as contributing to reduced global oil demand.

* The Paris-based organisation also pointed to reduced demand by India and Indonesia — key buyers of Nigerian oil.

ANGOLA

* Angola’s July loading programme was expected to emerge before the end of the week, while around 3 Angolan cargoes remain for June loading.

* Asian demand may be weighed down by a sharp widening of the Brent-Dubai spread DUB-EFS-1M over the past week and steep backwardation.

* Most traders believe China has few alternatives for Angola’s heavier oil grades, which are scarce in the global market because of U.S. sanctions on Iran and Venezuela.

TENDERS

* Turkey’s Tupras issued a buy tender for a cargo of west African crude for delivery between June 25 and July 10. It was set to close on Wednesday.

* India’s IOC has two buy tenders for crude loading July 7-16 and June 22 to July 1, closing on Thursday.

RELATED NEWS

* The world will require very little extra oil from OPEC this year as booming U.S. output will offset falling exports from Iran and Venezuela, the International Energy Agency said on Wednesday.

* China’s crude oil throughput rose in April to match record daily levels, government data showed on Wednesday, buoyed by growing production at private refiners, including a mammoth new facility in the country’s northeast. (Reporting by Noah Browning; Editing by Kirsten Donovan) ))
